Abstract: Real-Time Interpretation Improves E&P Decision Making
By
CogniSeis Development
Real-time interpretation has significant
implications for the E&P industry. The
ability to reach an interpretation while fundamental
exploration and production processes
are underway holds the promise of
substantially improving outcome while
acquiring data, drilling wells, and managing
reservoirs. "Real time" means that data
can be visualized and interpretations performed
during acquisition, processing,
drilling, and production. "Interpretation" in
this context includes all the tasks needed
for forming a consistent 3-D subsurface
model
: data processing, analysis, modeling
structural and stratigraphic interpretation,
reservoir simulation, and
model
integration
with production data.
The benefits of real-time interpretation are
significant. If interpretations are performed
while acquisition is underway, the turnaround
time for drilling decisions can be
significantly shortened. In addition, navigation
and seismic data can be quality
controlled much more effectively with full
processing interpretation during the acquisition
phase. With respect to drilling, not
only can the target area be hit more effectively
if it is visualized, but there is a substantial
reduction in blowout risk with
real-time interpretation. Finally, reservoir
management can be done much more
effectively with the ability to continuously
update the model
during production.
To achieve real-time interpretation, new information technology is needed. Real-time 3-D data processing during acquisition requires fast parallel computers together with appropriately parallelized software. Effective utilization of different data types from separate locations requires new information access tools such as interactive video teleconferencing. The ability to visualize 3-D data with embedded interpretation requires new voxel-based technology. Synthesis of all data types and interpretation requires a software framework such as TerraCube, OpenWorks, or GeoFrame.
The goal for real-time interpretation is to improve outcome through better and faster decisions. The method for achieving this goal is to use new technology to provide a more accurate and comprehensive understanding of the subsurface and to minimize time spent by the interpreter searching for projects, reformatting data, and learning new software. The user remains the critical element of the system because it is the user who exercises the judgment, imagination, and creativity to make final decisions, and it is the user who will make these decisions in real time while processes are underway in order to improve outcome.
